Restricted capacities

Entitled Definition Publication

CMNTt Technical minimum capacity available in the event of

engineering works.

At last 60 days before (1st)

Can decrease until DW-5

Can increase until D-1

CPRTt Probably capacity available in the event of works. At last 60 days before (1st)


CTE Technical effective capacity.

Its the actual total technical capacity on a PCR that GRTgaz

can actually guarantee to all shippers per Gas Day. It can differ

from the CTN* in the event of restrictions.

On D-1 before 2 pm

Can increase until the beginning of the Gas

Day in case of the end of works.

COSf Firm capacity subscribed by all shippers for a Gas Day -

Max TRf Maximal firm flow restriction

Max TRf = 1 – CMNTt / COSf


Can decrease until DW-5


Probable TRf Probable firm flow restriction

Probable TRf = 1 – CPRTt / COSf



15

Reductions of capacities caused by works are published in the GRTgaz work program*.

The following values are published:

* - http://www.grtgaz.com/en/acces-direct/customer/supplier-trader/works.html



Restricted capacities

The CMNTt* represents the technical minimum capacity available in the event of works.

Its calculation is based on a situation of extreme network requests in terms of

consumption and programming of flows. It also integrates a reasonable estimation of

potential hazards of the works.

The CPRTt* gives a good view of the available capacity on a situation of reasonable

network requests. More exactly, its based on median consumptions and flows scenario

and takes now into account probabilities on works.

Before 2:00 pm on D-1, CTE* value gives the final capacity available from GRTgaz for

Day D.

From DW-5, the CTE cannot be lower than the CMNTt. However, CTE can be higher

than the CPRTt if the conditions make it possible.

Restriction rates

From 19th of March 2019 GRTgaz republish the PITS

restriction rates on Trans@ctions*.

Moreover restriction rates remain available for consultation

on Smart GRTgaz.

These restrictions rates are only the GRTgaz vision and are

calculated with the operational subscribed capacities.

The mutualised restriction is triggered for the cycle H+2-H+4 if:

Locational spread is contracted even if

not successful!

- The locational spread launched at H is not successful

- AND the alert level is still red at H+1

No other locational spread is launched if the former one is not successful!

Mutualised restriction is activated only if the locational spread is not sufficient




Mutualised restriction principles

54

As a last resort, within the day, should the call to the market via thelocational spread not be effective

No financial compensation in the event of use of this mechanism

Partial interruption of firm capacities:

▪ pro rata to the subscribed capacities

▪ mutualised on a group of points called superpoint, in order to give flexibility to theshippers

• PITS impacted are scheduled with a new status
